The best would be to replace the LNB with a SLNB and not use the Explora switch. This will allow you to combine both the Explora 1 and 2A under XV. Best if the Explora 2A is made the primary decoder. The HD PVR now becomes obsolete as it cannot be combined with the two Explora decoders under XV.
The 60 cm antenna should be okay provided the antenna has been aligned properly.
